Thanks for the explanation. I've changed the code to use the data length: case HTTP_EVENT_ON_DATA: ESP_LOGI(TAG, "HTTP_EVENT_ON_DATA, len=%d, chunked: %d", evt->data_len, esp_http_client_is_chunked_response(evt->client)); /* * Check for chunked encoding is added as the URL for chunked encoding used ...

Hi, I am trying to connect to a webpage using username and password and the esp_http_client_example.c. The webserver responds with content length of -1 and I don't know how to proceed. My end goal is to login to the webpage (it's a local energy meter) and read the HTML. The debug log is below. I'll ...

@boarchuz, how do you manage to parse a segmented file on-the-fly?

I am faced with the same situation, where I need to use regex to find a value in HTML, which is way too big for fitting into RAM.

I am trying to use http_client for downloading files in a RAM buffer. My code allocates a user_data buffer for the esp_http_client_config_t handle, however my application crashes due to heap poisoning: CORRUPT HEAP: Bad tail at 0x3ffdb255. Expected 0xbaad5678 got 0x6c617265 assert failed: multi_heap...

Thanks for the quick reply, the problem seems the same.

The code breaks at the following line of spi_master.c: I'll try the proposed workaround.

I have a board with three SPI devices on Host 3 (VSPI), using pins 18 for clock, 23 for MOSI, and 19 for MISO. Clock is 10 MHz: W5500 Etherned module, CS 33 SD card, CS 25 MPC23S08 GPIO expander, CS 32 My code begins with initializing the SD card, then the expander and finally the Ethernet chip. I o...

A generic MPC23S08 driver with example for espidf here.

I have a custom board which has a W5500 and SD card on the same SPI host. Pins are: SPI Host - 2 SPI Speed - 12 MHz SCLK - IO 18 - NO PULL-UP MOSI - IO 23 - NO PULL-UP MISO - IO 19 - NO PULL-UP W5500 CS - IO 33 - PULLED UP W5500 INT - IO 13 - PULLED UP W5500 RST - IO 12 - PULLED DOWN SD Card CS - IO...

Thanks for the link, haven't tried that. I am using espidf, not Arduino, it would probably not be a solution.

I'm looking for recommendation for Modbus TCP master library for ESP32. I can't use the embedded API, as I am already using Modbus RTU.

Thanks
